Notes. Columns are as follows: (1): population ID; (2): number of galaxies in a population; (3): percentage of VO galaxies in a population; (4–5): median values of the stellar mass for VO and YS galaxies; (6–7): median values of the stellar velocity dispersion σ^* for VO and YS galaxies; (8–9): median values of the concentration index C for VO and YS galaxies; (10–11): median values of the D_n(4000) index D_n(4000)_med for VO and YS galaxies. (12–13): median values of SFR index SFR_med for VO and YS galaxies.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
